| Abstract: | The neurogenic pulmonary edema is a rare clinical situation caused by an imbalance characterized by an excessive sympathetic outflow. It is observed mostly in young patients, is associated with brain or spinal cord haemorrhage, trauma, tumours or infections and is usually fatal. A case of neurogenic pulmonary edema in a 27-year-old woman is presented, caused by a cerebellar haemorrhage due to a vermian and paravermian arteriovenous malformation rupture. The vermian and hemispheric haemorrhage injuring the sub-lobule IX-b of the uvula induced a disruption of both carotid baroreceptor and chemoreceptor reflexes control mechanisms. Medical treatment with controlled ventilation, PEEP, diuretics and morphine reverted the pulmonary edema. After surgical treatment of the haemorrhage and cerebellar AVM the patient recovered to an almost normal social and professional life. The cerebellar lesion induced a temporary vermian sub lobule IX-b dysfunction that was responsible for the sympathetic storm that evoked the neurogenic pulmonary edema. |
